Understanding portable diesel heating
What is a portable diesel air heater?
Cube Gen 3 combines the heater, controls and an integrated 5 L diesel tank in one rugged portable unit. It burns a small amount of diesel in a sealed combustion chamber while the 12 V or 24 V electrical system powers the fan, fuel pump and controls.
The sealed combustion chamber heats the unit’s heat exchanger.
A fan circulates air across the heat exchanger and distributes warm air through the ducting.
Cube is a portable air heater: it warms the surrounding space directly rather than heating a vehicle coolant circuit.
Correct installation is essential: combustion air and exhaust gases must remain separated from the heated space.
Cube Gen 3 highlights
Portable design. Quieter operation. Smarter control.
Cube Gen 3 combines a portable all-in-one design with quieter operation, upgraded installation components and a choice of Bluetooth or Wi-Fi + Bluetooth control.

Included with every Cube Gen 3
SuperSilent fuel pump
Less ticking. More comfort.
The included SuperSilent fuel pump is designed to reduce the repetitive ticking noise associated with conventional diesel-heater fuel pumps, helping create a quieter installation.
